1.
Determine how many degrees you need to increase or decrease the Top-stop angle.
•
If the press top-stops after 0°, you should increase the Top-stop angle by the number of
degrees beyond 0° that the ram stops at the slowest press operating speed.
•
If the press top-stops before 0°, you should decrease the Top-stop angle by the number
of degrees before 0° that the ram stops at the slowest press operating speed.
2.
Install the heaviest upper die in your press. Adjust the counterbalance for ram weight (if
the press has a counterbalance).
3.
With WPC 1000 powered up and the press in Inch mode, press the Reset/Select button
repeatedly until the “Top Stop Angle” indicator is lit.
4.
Set the Top-stop “On” Angle you determined in step 1, using the WPC Settings key
switch. Turning the key to “+” (counterclockwise) increases the angle; turning the key to
“–” (clockwise) decreases the angle.
5.
Run the press in Continuous mode by turning the Mode Select switch to “CONT,”
checking the press speed shown in the LED display.
If your press does not run in Continuous, initiate a stroke with the Mode Select switch set
to “SINGLE.”
6.
When the press reaches normal operating speed in Continuous or the Auto Carry-up Angle
is passed in Single-stroke, Top-stop the press. Note the crankshaft angle shown in the
LED display.
If the Top-stop angle is 0° ±2°, go to step 7.
If the Top-stop angle is more than 2° beyond 0°, repeat steps 3 through 6 until the press
top-stops at 0° ±2°.
7.
Repeat step 6 at least five times to make sure that the press top-stops at 0° ±2°.
CHECK OVERRUN SENSOR SETTING WHEN YOU CHANGE TOP-STOP ANGLE
Check and reset the overrun sensor angle when you reset the Top-stop angle. Remember
that the Top-stop angle has an internal dwell of 20°. The internal Top-stop timing turns off
20° after the Top-stop angle that you set. This internal Top-stop timing must turn off before
the overrun sensor turns on. If the Top-stop timing and the overrun sensor are “on”
simultaneously, an “80 series” error code will display (see page 5-16).
